Every night on Mars, when the sun sets and temperatures fall to minus 80 degrees Fahrenheit and below, an eerie phenomenon spreads across much of…
Vast areas of the Martian night sky pulse in ultraviolet light, according to images from NASA’s MAVEN spacecraft. The results are being used to illuminate…
At the heart of understanding our space environment is the knowledge that conditions throughout space — from the Sun to the atmospheres of planets to…
Five years after NASA’s MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric…
Mars had a global magnetic field much earlier—and much later—in the planet’s history than scientists have previously known. A planet’s global magnetic field arises from…
NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft has discovered “layers” and “rifts” in the electrically charged part of the upper atmosphere (the ionosphere) of…
Researchers have created the first map of wind circulation in the upper atmosphere of a planet besides Earth, using data from NASA’s MAVEN spacecraft that…
Auroras appear on Earth as ghostly displays of colorful light in the night sky, usually near the poles. Our rocky neighbor Mars has auroras too,…
How long might a rocky, Mars-like planet be habitable if it were orbiting a red dwarf star? It’s a complex question but one that NASA’s…
NASA’s MAVEN Spacecraft reveals that Mars has an invisible magnetic “tail” that is twisted by interaction with the solar wind. NASA’s Mars Atmosphere and Volatile…
An unexpectedly strong blast from the Sun hit Mars last month, sparking a global aurora more than 25 times brighter than any previously seen by…
New results from NASA’s MAVEN spacecraft reveal that solar wind and radiation are responsible for stripping the Martian atmosphere, transforming Mars from a planet that…
New images from the MAVEN mission show the ultraviolet glow from the Martian atmosphere in unprecedented detail, revealing dynamic, previously invisible behavior. They include the…
New observations from NASA’s MAVEN Mission has scientists closer to solving the mystery of how Mars’ moon Phobos formed. In late November and early December…
NASA’s MAVEN mission reveals that solar wind appears to have played a key role in the transition of the Martian climate from an early, warm…
At 2 p.m. EST on November 5 NASA will provide details of key science findings from the agency’s ongoing exploration of Mars. The event will…
NASA is working on the technology that will enable an actual trip to Mars in the 2030s. On August 7, 1972, in the heart of…
NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft completed 1,000 orbits around the Red Planet on April 6, four-and-a-half months into its one-year primary mission….
